Given,
The total number of student got C is 15.
The total number of students is 61.
Required
The probability of getting C.
The probability of getting C is,
[tex]\begin{gathered} Probability=\frac{total\text{ number of students with C}}{total\text{ students}} \\ =\frac{15}{61} \\ =0.246 \end{gathered}[/tex]Hence, the probability of student getting C is 0.246.
